residi gi" at Gary, in the county ot' Lake and State of indiana, bothcitizens of the United States or' .'liinegrica, have invented a certainnew and useful Improvement in Coke-Oven and Charging lvieehaniem, ofwhich the following' is a` specification.

This invention relates to coke ovens and to machinery for charging them.The olojert of the invention is to provide -a coke oven and a chargingmachine therefor so constructed that the material delivered into 1theoven is inueh more evenly distributed in the oven than has heretobeforebeen possible, thus doingv away with the large amount of laborheretofore required in spreading the material alter it has beendelivered into the oven, and in eleaningE up the coal on top of l' theovenY after the chargingr operation. A

rfurther olijeet is to so Construct the device that a .inueh largervolume of material may he charged at one time, thus greatly saving thetime the oven is out of commission.. and

s is well understood in the art, a ACoke -to root- 'each ot thesecompartments `with solid lirici( perforated at intervals. with holestl'irough which coal is delivered, said Coal falling in conical piles atintervals along' coal Chambers from which condition it had. to beleveled off by mechanism ordinarily operating; through the end of theCoal eliarnf her at considerable trouble and eriense. Furthermore. anoperator had to Walk along the top of each coal chamber, sweep into thesurplus material left on the top in .the process oi delivering coal intoit.r and then put in hy hand circular covers to close the coal Chamberpreparatory to the operation of coke making. ln Construction shown inthis application. the upper or roof section of the coal chamber isreplaced 'o v .i compartment havingn at its cxtreme ends adiagrammatifallv indicated Wall l/l. Fig'. l connected by lonarparallelside lWalls 16 rising' from the top portionlfl of the coalchamber proper g] l l and open continuously into said such coal chamber.This top or supplemental roof passage is of appproximately thedimensions of the coal chamber to 'be `filledv and as the lengths of theside Walls 16 are therefore substantial it is necessary to tie themtogether. rllhis is done by two classes of intermediate Walls; 20,having through them gas passages 22 and carrying at their tops trackrails 24 over which the charging machine passes; and 26 preferablysharpened at their tops in points 28 to assist in breaking up anddistributing the coal passing down through the roof box 14--16 into thecoal chamber proper.-

It will, of course, be understood that the oven proper consists of amultiplicity of such coal chambers placed sideby side and consequentlythere are a plurality of these roof passages, one for each coalchamber,y placed side by side as clearly appears in F ig. 2. Adjacentchamber walls are tied together by metallic tie rods 32 which, in thecase of the Walls 20 carrying the rails 24,

lie immediately belou7 the rails. as shown in Fig. i. In Fig. 2 thenumeral 34 indi- Cates the iiue from the heating chambers (not shown)which areV in the complete furnace or oven, forming no part of thisinvention, placed between the adjacent coal chambers.

The rectangular top openings left between the ivalls 16 and the Walls 2Oare selectively closable by rectangular doors 36 which are in theconstruction heretofore used about 9 inches Wide and 8 feet long, andare equipped with downwardly beveled edges 38 adapted to insure tightiit when lowered to place as shown in Figs. 5 and 6.

Considering the oven construction thus :tar described, it will be seenthat by passing al proper machine over the oven top and dumping coaluniformly along the reotangular openings closed'by these doors 36, astream ot coal substantially the length of the coal chamber can bedelivered into it and that said coal in passing downward said openingsto and through the passages 30. will engage the points 28 of the Walls26 and he broken up and thus fall in as near as possible an even showerinto vthe coal pit below, with the result that the resulting pile in thecoalchamber will be nearly, it not quite evenly, distributed and requirepractically no leveling. Even if some manual leveling be required. theopenings closed by theI doors 86 are so much larger than the circularholes heretofore provided that such manual leveling is greatlyfacilitated With consequent saving oi' time and energy.

In order to obtain the advantages of the oven roof construction justdescribed.' a. charging mechanism is provided carried by a car travcling along the rails .24, heretoiore referred to, said carbeing ofsuch dimensions that all or the charging openings of a. single coal.chamber may be simultaneously charged with coal. The particularembodivment ot the car shown in the drawings coinprises a rectangularframe 40 ot any suitable constructionY mounted on the wheel 42 travelingfrom coal compartment to coal compartment ot' the battery or oven overthe rails 24.

Supported on this truck frame 4U by any suitable means such, forinstance, as the construction 44, 46 is a `coal compartment or chamber48 extending the length ot the car and `the length of the coal chamberto be charged having at its top intake openings 50 for the reception ofcoaland at its bottom a plurality of longitudinally arranged dischargeports 52, one for each-of theopenings in the oven top closable by thedoors 36.

vThis coal chamber 48 is made of known predetermined coal capacitythereby dispensing with the necessity of Weighing the coal about to beinserted in the coal chamber. In ordinary practice chamber 48 is made otexactly the right size to take the proper amount oi coal for charging a.given coal chamber of the coke oven. It is therefore necessary only tobring one load to each coal chamber in order to charge the entire cokeoven. In charging an oven a train of cars equipped ivith coal chambers48 may be passed over the oven one car being discharged into each coalchamber or the saine car may be sent back and reloaded and successivelyused in charging successive coal chambers Without departing from thisinvention.

Pivoted on suitable brackets 54 on opposite sides of discharge chute orpassage 52 are doors 56 or'closing the bottom of the chute andcontrolling the discharge of coal from coal chamber 48. -The ends ofthese doors 56 are equipped With end members 58. Fig. 8. provided withslots 60 in which crank pin bolts 62 on the ends of connecting rods 64are adapted to slide. These connecting rodsare adjustable in lengththrough the threaded links 66 clearly shown in Fig. 8. The opposite endsof these connecting rods are mounted on. 'the end of' a crank arm 68, ona shaft 70. driven by a worm gea-r 72, driven by a Worm 74. on a rod 76,operated by a hand wheel '78. located within the operator`s cage orhouse 80. The operator can by properly turning this wheel 78 open andclose doors 56 for obvious purpose of controlling` the discharge ot coalfrom chamber 48. Shaft 70, just referred to. also carries the lever arm82 on whose outer' end is a.. counter weight 84 detachably .adjustablealong slot 86., This eounterwei'glit serves the function of normallyholding the doors 56 closed witlioit the strain thereof being carried bythe gear mechanism 72. 74.

The operatos house or cage 8O also contains car driving' mechanismwhichin the :useable particular case here illustrated is merely anelectric motor 88 driving one of the Wheels 24 through the sprocketoliain mechanism 90. The controller for the motor 8S is indi cated at92.

intermediate between the ear frame Ai() and various parts heretoforedescribed7 are stationary beams 94 and S96 at rightl angles to eachother. Supported on beams 94 are cross beams 102, one pair ol such beamsfor each oi the two lifting (cylinders 101. llaeh one oi' thesecylinders 104 operates a vertieal piston rod 10G ou'whoselower end is aCross head meehanism, made up of parallelfbeams 98, 'irojeetingarm 108.,and rollers 110 traveling on guides 112 depending from beams 9-1 andconnected together at their lower` end by .cross member 111i. Extendingparallel with the beams 9S and inside the guides 112 is an angular rod100, reelproeatively mounted ou brackets 11G7 which are in turn vmountedon 'beam 98.

Rod 14)() is driven bach and for" Ward at the will of the operator bymanipre latinoF hand lever 11S piroted on the bottom ot beam 98 at12A),A there being pin and slot connections 1F32S rod. Between the beamsS8 and at points remote 'from the suspension mechanism 10G are blot-ks12e in Whieh are rotatably mounted Vertical siialits 1536. These Shaftsare rotatable through approximately 90 by being" equil'iped.with leverarms ll connected to rod lill) through pin and slot connections 130eleaily appearinglf in Fig. 1 0. These .shafts 126 are located along theoar one to eaoh end of eaeh door 3b. (in the bottom of each shalt: 126is an elongated button 182 adapted to be turned by the reoiprcmation ot'the rod 100 between two }iositi iiis,-in one of which it freely passesthrough the spare or buttonliole 134 between angular liaugre members 13Gattached to the door, and in the other of which it is in the positionshown in, t3, behind said Hannes and leonsequently eures the door to theadjacent shaft 1% so that 'vertical movement of the shaft Will lift thedoor. l

rllhis reeiproeation of the shafts and lifting the door obviously'talles place when the operator manipulates the air or other source or'power in cylinders 1041 to lift pistou rods 106 and consequently beams98. ln the particular construction shown in the drawings cylinders 10iare supplied with air through au air Compressor 140 operated by a motorl14112 controlled by the operator iu his cage through Wires eoutained iupipe 111. Pipingf 146 is that by which the compressor 140 supplies andoperates cylinders 10ft.

general operati/m. i

rllhe operator haring' his ear loaded with coal, in compartment' 48 andthe doors 56 elosed as shown in Fig. i2 and with beams 98 drawn up showniu Fig. 1 but without the between the lever and the doors attachedthereto. turns on power to -drive the ear overthe partieular coal ellam--ber oli the oven which is to be charged with lates the'air in thecylinders 10e to lift all" the doors 36 to the position. shown inFig. 1. He new moves his car along the track until Chute 54 is over thedoor openings, extending lengthwise of the eoal receptacle. ,He

nou takes hold of wheel 78. opens the doors 56. whereuliou the' contentsot' chamber 48 slides into the oven opening through the passages 30heretofore deseribed. and, evenly distributes itsel'l2 along the lengthof the eoal receptacle. The operator new manipulates handle 7S to elosedoor 5G, then moves his oar until the doors 36 are ,over theirrespective entrances to the coal receptacles. whereupon he reverses hisoperation of oylinder 104, lowers the doors to closed position, and thenreverses lever 11S thus releasingI the buttons 132. lele thenmanipulates cylinders 101 to raise the shafts 1526 to original position'whereupon he is ready to move his ear on to get another load ot eoal vf As shown in Fig. 1 floors 3d are all in line with each other and arereferred to as alined.' Similarly doors 56 extend end to endI across thehopper and are alined.l
